Project Runway Season 17 is set to premiere in 2019. Klum and Gunn had previously starred on all 16 seasons of Project Runway which returned to Bravo in May. The series had moved to Lifetime in 2008 after airing for five seasons on Bravo.

"As someone who grew up watching Project Runway, I could not be more excited to host and produce a series that provides a platform to aspiring American designers as they pursue their creative and entrepreneurial dreams," Kloss said in a statement.

"I am equally as thrilled to work alongside an incredibly talented group of fashion innovators - Brandon Maxwell, Elaine Welteroth, Nina Garcia and Christian Siriano - to inspire, support and help guide these designers as they realize their visions and build everlasting brands and businesses," she continued.

"Project Runway has offered such wonderful opportunities for so many and I'm excited to take on this role as a mentor. I hope to guide and inspire the new talent on the rise," Siriano said.
